{"abstract":"We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. This proposed AD would require visually inspecting certain subfloor frames for a crack. This proposed AD is prompted by reports of cracks on in-service helicopters. The proposed actions are intended to detect or prevent a crack in the subfloor frame, which could result in failure of the pilot and co-pilot pedal support frame and subsequent loss of control of the helicopter.","action":"Notice of proposed rulemaking (NPRM).","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2015/06/05/2015-13354.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"80 FR 32072","comment_url":null,"comments_close_on":"2015-08-04","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by August 4, 2015.","disposition_notes":null,"docket_ids":["Docket No. FAA-2015-1935","Directorate Identifier 2014-SW-008-AD"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Various Supplemental AD Documents","document_id":"FAA-2015-1935-0002"}],"agency_name":null,"documents":[{"comment_count":0,"comment_start_date":"2015-06-05","updated_at":"2023-02-28T22:23:13.131-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2015-1935-0001","allow_late_comments":null,"id":"FAA-2015-1935-0001","comment_end_date":"2015-08-05","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2015-1935","title":"2014-SW-008-AD "}],"document_number":"2015-13354","effective_on":null,"end_page":32074,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2015/06/05/2015-13354.xml","html_url":"https://www.federalregister.gov/documents/2015/06/05/2015-13354/airworthiness-directives-agusta-spa-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-13354?publication_date=2015-06-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2015-06-05/2015-13354/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":511,"last_updated":"2026-04-04 08:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2015-06-05/pdf/2015-13354.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-13354.pdf?1433421921","publication_date":"2015-06-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2015/06/05/2015-13354.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"U.S. DOT/FAA - Various Supplemental AD Documents","document_id":"FAA-2015-1935-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2015-1935","supporting_documents_count":1,"docket_id":"FAA-2015-1935","document_id":"FAA-2015-1935-0001","regulation_id_number":"2120-AA64","title":"2014-SW-008-AD ","checked_regulationsdotgov_at":"2023-03-01T03:23:11Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":32072,"subtype":null,"title":"Airworthiness Directives; Agusta S.p.A.
